BERLIN (Reuters) - Russian sanctions against Germany in the case of the poisoned Kremlin critic Alexei Navalny are not justified, a German government spokesman said in Berlin on Friday. “A Russian citizen was attacked with a military nerve agent on Russian soil,” Chancellor Angela Merkel’s spokesman Steffen Seibert said.“Russia has all means at its hands to clear up this crime. Instead, the Russian foreign minister announces sanctions against officials of foreign countries,” he added. “From the perspective of the German government, such a step is obviously unjustified and inappropriate.”
